Tons of opportunities.
The town you live in- Mayor’s office. They can always use volunteers- dealing with constituents, helping to draft grant requests from foundations for specific uses, doing an analysis of spending this year vs. past five years, evaluating how traffic patterns changed during Covid, working with the local hospital/hospitals to understand if your city/town is leaving money on the table (i.e. more patients admitted with no health insurance, your state has a fund for the uninsured), etc.
Your state- dozens of issues, committees, state wide commissions and groups, lobbying organizations who target your governor for policy changes.
